METHOD OF MAKING PENCIL BARRELS Application filed June 25, 1923. SerialNo. 647,594.

graved into the barrel either by machines made for that purpose or byhand engraving the pencil barrel or casing.

In my invention I provide a method for applying the design or pattern tothe pencil casing 0r barrel in a manner so that it will simulate handengraving, engine turning, or chasing by a method which is not so eX-pensive as the methods heretofore used.

A. feature of the invention is in swaging the tubing to a writing pointafter it has i been decorated by my means of transferring the design orpattern unto the barrel or casing so that the decoration will extendover the writing point unto that part of the barrel which forms thewriting end and particularly over the part which is customarily engagedby the fingers of the person using the pencil in writing. By means ofthis method an economical means is provided for applying a decoration orpattern unto the pencil casing over the portion of the barrel where itis engaged by'the hand in writing, and this is a very desirable featurein metal barrel pencils, because it provides a better grip for thefingers to hold the pencil and prevents them from sliding off thetapered end while writing.

To more clearly illustrate my method of making the metal pencil barrelsIhave prd vided a drawing in which:

Figure 1 illustrates a perspective of the finished pencil barrel. e

Figure 2 illustrates a length of tubing used to make up the pencilbarrel before my method has been applied to the same.

Figure 3 illustrates the tubing in the first step of my method of makingthe same.

Figure 4 is an enlarged detail of the forward writing end of the pencilbarrel in finished form, a

Figure 5 is a section on line 55 of. Figure3. i

In carrying out mymethod the metal tubing which is to be used for makingthe pencil barrel or casing is of the desired dimensions, having auniform cross section and vcontour throughout its length. This tubing iscut into the desired lengths such as A and is then passed through thechasing machine, engine turning machine, or may be hand engraved so thata design or pattern is impressed or engraved into the barrel or casingjA It is not essential in carrying out my method that the tubingfirst becut into the desired lengths for individual barrels, but it may bepreferred where the ordinary chasing machinery is used. The tubingcan besubjected to method in the long lengths in which it is supplied from thetubing factory, so that the'pencil barrels can be made automaticallyfrom the original lengths, each step of the method being carried out asthe same progresses so that the finished pencil. barrels will becomplete at the'end of the operation. p v

If it is desired to impressthe barrel A with a design such as B,illustrated in Figure 3, by means of the ordinary chasing machine wherethe :design is applied to the barrel by pressure, the tubing or barrel Ais passed through the chasing machine so chine may be of anydesiredw-ell known con- 7 struction, Obviously, the design B can be engraved byan engine turning machine, or-

any other-design applied by such a machine or the design B may be handengraved, par ticularly that part including the scrolled lines whichmake up the particular design on the pencil barrel.

After it has been chased or engravedand it is: in the form illustratedin Figure 3, it is hen waae o e nd to form the and or tip C. The swagingof the tubing extending back and including a portionof the engraved partof the barrel so that the pattern or design is engraved over thatportion which is engaged by the fingers in using the pencil. The extremeforward end of the appear as it is illustrated in the drawing in Figure1 and it will be readily apparent that the extending of the designoverlthegripping portion of the barrel provide's'an advantage not onlyin giving a better holding surface for the fingers, but in theappearance of the pencil barrel, particularly by reason of the factthatthe design" converges toward the point in a uniform manner andthereby makes a design much more attractive on the pencil casing orbarrel than if it stopped abruptly at a point in advance of the curvedportion which tapers into the writing'tip.

Pencil barrels have been made heretofore with the engrav ng extendingover the writing tip or end of the same, but'these have either been madeby hand engraving or by engine turning machines; which is a slow processof operation and cannot be extended as far over the writing end as iscarriedout in my method. Hand engraving is very expensive and the engineturning isafslow method of engraving and decorating the barrels. lilymethodis very rapid and bymeans.

of suitable die wheelsin the ordinary chasing machines the patternor'design can be transferred unto the barrel very rapidly. The curve ortaper formed on the writing end of the pencil by swaging it to form awriting 'tip decreases the'di'ameter toward the pointand for thesereasons it. is imprac ticable to use a machine forengravingfor chasingthe pencilbarrel after itis formed and swagedfwitlrtl e finished writingtip. The engine turning machines now-in use will engrave'over thewriting end a short distancefbut are not practical 'to carry the patternfar down on the writing tip 'of-the pencil barrel. Itis also'veryimportant to consider that in these engine turning machines the patternis engravedby a diamond point and is usually made up by'a combinedlongitudinal and transverse movement and each line is made by' aseparate andzdistinct. stroke of the machine which accounts for the timethat is required-to cha se eaehbarrel. My invention obviates all ofthese undesirable details and permits the pencil barrels to berrapidlychased or engraved with pat terns or designs and not swaged in theregular ordinary well known manner, making a saving of more than half ofthe time required tO 'fiDiSlI the pencil barrel and pro-- riding adesign which is even more attractive than where the design is applied byan my inventioinl desire to have it understood I that this isonlyillustration and that the invention can be carried out and applied touses other than those above set forthwithin the scope of the followingclaims.
